OE sensor的用法和样例：
例句
- The reflector will be vibrated when the object is slipping,thus the output signal of the photoelectric sensor will be changed.
当物体有相对滑动时会引起反射镜面的振动，由此引起光电传感器的输出信号发生变化。 - When the pest crawls through the electro-optical sensor, it will produce a high level signals and begins to count the pulse signal, the count to the pest's number can be realized.
当虫子通过光电传感器时，光电传感器输出高电平信号对脉冲信号进行计数，就实现了对虫子数量的统计。
